Accordingly, those of ordinary skill in the art will recognize that modification, equivalent, and/or alternative on the various embodiments described herein can be variously made without departing from the scope and spirit of the present disclosure. With regard to description of drawings, similar elements may be marked by similar reference numerals.

In this disclosure, the expressions “have”, “may have”, “include” and “comprise”, or “may include” and “may comprise” used herein indicate existence of corresponding features (e.g., elements such as numeric values, functions, operations, or components) but do not exclude presence of additional features.

In this disclosure, the expressions “A or B”, “at least one of A or/and B”, or “one or more of A or/and B”, and the like may include any and all combinations of one or more of the associated listed items. For example, the term “A or B”, “at least one of A and B”, or “at least one of A or B” may refer to all of the case (1) where at least one A is included, the case (2) where at least one B is included, or the case (3) where both of at least one A and at least one B are included.

The terms, such as “first”, “second”, and the like used in this disclosure may be used to refer to various elements regardless of the order and/or the priority and to distinguish the relevant elements from other elements, but do not limit the elements. For example, “a first user device” and “a second user device” indicate different user devices regardless of the order or priority. For example, without departing the scope of the present disclosure, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element.

It will be understood that when an element (e.g., a first element) is referred to as being “(operatively or communicatively) coupled with/to” or “connected to” another element (e.g., a second element), it may be directly coupled with/to or connected to the other element or an intervening element (e.g., a third element) may be present.

FIG. 1 illustrates an electronic device in a network environment system, according to various embodiments.

Referring to the non-limiting example of FIG. 1, according to various embodiments, an electronic device 101, a first electronic device 102, a second electronic device 104, or a server 106 may be connected each other over a network 162 or a short range communication 164. The electronic device 101 may include a bus 110, a processor 120, a memory 130, an input/output interface 150, a display 160, and a communication interface 170. According to an embodiment, the electronic device 101 may not include at least one of the above-described elements or may further include other element(s).

For example, the bus 110 may interconnect the above-described elements 110 to 170 and may include a circuit for conveying communications (e.g., a control message and/or data) among the above-described elements.

The processor 120 may include one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP). For example, the processor 120 may perform an arithmetic operation or data processing associated with control and/or communication of at least other elements of the electronic device 101.

The memory 130 may include a volatile and/or nonvolatile memory. For example, the memory 130 may store commands or data associated with at least one other element(s) of the electronic device 101. According to an embodiment, the memory 130 may store software and/or a program 140. The program 140 may include, for example, a kernel 141, a middleware 143, an application programming interface (API) 145, and/or an application program (or “an application”) 147. At least a part of the kernel 141, the middleware 143, or the API 145 may be referred to as an “operating system (OS)”.

For example, the kernel 141 may control or manage system resources (e.g., the bus 110, the processor 120, the memory 130, and the like) that are used to execute operations or functions of other programs (e.g., the middleware 143, the API 145, and the application program 147). Furthermore, the kernel 141 may provide an interface that allows the middleware 143, the API 145, or the application program 147 to access discrete elements of the electronic device 101 so as to control or manage system resources.

The middleware 143 may perform, for example, a mediation role such that the API 145 or the application program 147 communicates with the kernel 141 to exchange data.

Furthermore, the middleware 143 may process task requests received from the application program 147 according to a priority. For example, the middleware 143 may assign the priority, which makes it possible to use a system resource (e.g., the bus 110, the processor 120, the memory 130, or the like) of the electronic device 101, to at least one of the application program 147. For example, the middleware 143 may process the one or more task requests according to the priority assigned to the at least one, which makes it possible to perform scheduling or load balancing on the one or more task requests.

The API 145 may be, for example, an interface through which the application program 147 controls a function provided by the kernel 141 or the middleware 143, and may include, for example, at least one interface or function (e.g., an instruction) for a file control, a window control, image processing, a character control, or the like.

The input/output interface 150 may play the role, for example, of an interface which transmits a command or data input from a user or another external device, to other element(s) of the electronic device 101. Furthermore, the input/output interface 150 may output a command or data, received from other element(s) of the electronic device 101, to a user or another external device.

The display 160 may include, for example, a liquid crystal display (LCD), a light-emitting diode (LED) display, an organic LED (OLED) display, a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 160 may display, for example, various contents (e.g., a text, an image, a video, an icon, a symbol, and the like) to a user. The display 160 may include a touch screen and may receive, for example, a touch, gesture, proximity, or hovering input using an electronic pen or a part of a user's body.

For example, the communication interface 170 may establish communication between the electronic device 101 and an external device (e.g., the first electronic device 102, the second electronic device 104, or the server 106). For example, the communication interface 170 may be connected to the network 162 over wireless communication or wired communication to communicate with the external device (e.g., the second electronic device 104 or the server 106).

The wireless communication may use at least one of, for example, long-term evolution (LTE), LTE Advanced (LTE-A), Code Division Multiple Access (CDMA), Wideband CDMA (WCDMA), Universal Mobile Telecommunications System (UMTS), Wireless Broadband (WiBro), Global System for Mobile Communications (GSM), or the like, as cellular communication protocol. Furthermore, the wireless communication may include, for example, the short range communication 164. The short range communication 164 may include at least one of wireless fidelity (Wi-Fi), light fidelity (Li-Fi), Bluetooth, near field communication (NFC), magnetic stripe transmission (MST), a global navigation satellite system (GNSS), or the like.

The MST may generate a pulse in response to transmission data using an electromagnetic signal, and the pulse may generate a magnetic field signal. The electronic device 101 may transfer the magnetic field signal to point of sale (POS), and the POS may detect the magnetic field signal using a MST reader. The POS may recover the data by converting the detected magnetic field signal to an electrical signal.

The GNSS may include at least one of, for example, a global positioning system (GPS), a global navigation satellite system (Glonass), a Beidou navigation satellite system (hereinafter referred to as “Beidou”), or an European global satellite-based navigation system (hereinafter referred to as “Galileo”) based on an available region, a bandwidth, or the like. Hereinafter, in this disclosure, “GPS” and “GNSS” may be interchangeably used. The wired communication may include at least one of, for example, a universal serial bus (USB), a high definition multimedia interface (HDMI), a recommended standard-232 (RS-232), a plain old telephone service (POTS), or the like. The network 162 may include at least one of telecommunications networks, for example, a computer network (e.g., LAN or WAN), an Internet, or a telephone network.

Each of the first and second electronic devices 102 and 104 may be a device of which the type is different from or the same as that of the electronic device 101. According to an embodiment, the server 106 may include a group of one or more servers. According to various embodiments, all or a portion of operations that the electronic device 101 will perform may be executed by another or plural electronic devices (e.g., the first electronic device 102, the second electronic device 104 or the server 106). According to an embodiment, in the case where the electronic device 101 executes any function or service automatically or in response to a request, the electronic device 101 may not perform the function or the service internally, but, alternatively additionally, it may request at least a portion of a function associated with the electronic device 101 from another device (e.g., the electronic device 102 or 104 or the server 106). The other electronic device may execute the requested function or additional function and may transmit the execution result to the electronic device 101. The electronic device 101 may provide the requested function or service using the received result or may additionally process the received result to provide the requested function or service. To this end, for example, cloud computing, distributed computing, or client-server computing may be used.

According to certain embodiments, if the target application does not support resizing, the processor 450 may configure a second type of window with a fixed size, based on the modified screen configuration information and the execution screen of the target application. For example, the processor 450 may configure the second type of window, which includes the execution screen of the target application, in a partial area of a landscape screen with 1920×1080 (FHD) and 160 dpi (MDPI). For example, the processor 450 may configure the second type of window with the same size as that of the touch screen display 410. In another example, the processor 450 may configure the second type of window with the same aspect ratio as that of the touch screen display 410. The processor 450 may generate, in a partial area of the screen, the second type of window that includes the execution screen of the target application and has the same configuration as that of the execution screen of the target application when the execution screen of the target application is displayed on the touch screen display 410.

According to various embodiments, the processor 450 may display the second type of window on the external display device 10 after the second type of window is configured. The processor 450 may display the second type of window, which includes the execution screen of the target application, in a partial area of the external display device 10. The processor 450 may provide the screen including the second type of window to the external display device 10. Resizing of the second type of window may not be allowed after the second type of window is output.

According to some embodiments, when an input is applied to a point in the second type of window, the processor 450 may recognize coordinates where the input is applied, may transform the recognized coordinates, based on the modified screen configuration information and the position of the second type of window, and may execute an operation of the target application that corresponds to the input to the transformed coordinates. The transformation of the coordinates will be described below in detail with reference to FIG. 16.

The normal mode launcher 740 may be executed in the case where the electronic device 400 is disconnected from an external display device. The normal mode launcher 740 may provide a UI and UX, such as a home screen displayed on the touch screen display 410.

The desktop mode launcher 750 may be executed in the case where the electronic device 400 is connected to an external display device. When the electronic device 400 is connected to the external display device, the desktop mode launcher 750 may provide an introduction to a desktop mode and may provide an execution or mirroring connection option of the desktop mode. The desktop mode launcher 750 may provide a UI or UX similar to a desktop displayed on the external display device. The desktop mode launcher 750 may support resizing of a resizable window.

The desktop mode launcher 750 may include a white list update service 751 and a white list database 752. The white list update service 751 may obtain, from a server, a white list that is a list of applications that support resizing. For example, the white list update service 751 may inquire the server as to whether the white list is updated, every specified period by using an alarm service after the desktop mode launcher 750 is executed. The white list update service 751 may obtain a URI of a white list file and may download the white list file by using an API provided by a contents cloud server. In another example, if the white list is updated, the server may convey the white list to a policy manager 763 in the framework 760. The policy manager 763 may store the white list in a policy database. The white list update service 751 may receive the white list from the policy manager 763 and may store the white list in the white list database 752. The white list database 752 may store the name of an application and/or a package that supports resizing. The white list database 752 may also store the name of an application that supports resizing, among the applications installed in the electronic device 400, and/or the name of a package that supports resizing.

The framework 760 may include a desktop mode service 761, a desktop mode policy manager 762, the policy manager 763, a window manager 765, an activity manager 766, and multi-window manager 767.

The desktop mode service 761 may obtain information associated with resizing of an application when the application is executed. For example, the desktop mode service 761 may obtain information about a declaration of resizing that is included in a manifest of the application, whether the application is a preload application or not, or whether the application is included in the white list.

The desktop mode policy manager 762 may receive the information obtained by the desktop mode service 761. Based on the received information, the desktop mode policy manager 762 may determine whether to generate a first type of window or a second type of window to display an execution screen of the application. The desktop mode policy manager 762 may convey the determination result to the desktop mode service 761, and the desktop mode service 761 may provide a service based on the received result.

The window manager 765 may modify the configuration 780. The window manager 765 may generate a window based on the modified configuration 780. For example, when the configuration 780 is modified, the window manager 765 may generate a configuration modification event and may generate a window based on the modified configuration 780. The window manager 765 may display icons for providing functions, such as back, minimize, maximize, and/or close, in a header at the top of the window. For example, when generating a resizable window (a popup window) that occupies a partial area of a screen, the window manager 765 may display icons for providing functions, such as back, minimize, maximize, and close, in a header at the top of the window. In another example, when generating a resizable window that occupies the entirety of a screen, the window manager 765 may display icons for providing functions, such as back, minimize, change to popup window, and close, in a header at the top of the window. In another example, when generating a non-rotatable window with a fixed size, the window manager 765 may display icons for providing functions, such as back, minimize, and close, in a header at the top of the window. In another example, when generating a rotatable window with a fixed size, the window manager 765 may display icons for providing functions, such as back, rotate, minimize, and close, in a header at the top of the window.

After the configuration 780 is modified, the activity manager 766 may obtain the modified configuration 780 from the window manager 765. The activity manager 766 may allow a resource manager to refine the resources 770, based on the modified configuration 780. The activity manager 766 may allow the application or activities included in the application to configure a screen based on the modified configuration 780.

The multi-window manager 767 may provide, for example, a window-related function not being supported by the window manager 765. For example, the multi-window manager 767 may generate a second type of window. In another example, the multi-window manager 767 may provide a function of minimizing a window. In another example, the multi-window manager 767 may generate an additional window including icons for providing functions, such as back, minimize, maximize, and/or close, and may dispose the additional window near the window in which the execution screen of the application is displayed.

The resources 770 may be resources of the activities included in the application. Activity resources 771 may include, for example, information about an image and a layout included in an execution screen of an activity modified based on the configuration 780.

The configuration 780 may include information about the density (dpi), orientation (landscape or portrait), and total size of a screen generated by the electronic device 400 and the size of the execution screen of the application. The configuration 780 may correspond to the activities included in the application.

The display info 790 may include information about a physical size (e.g., width and height) of a display.

FIG. 12 illustrates a screen provided by an electronic device according to certain embodiments of this disclosure.

Referring to the non-limiting example of FIG. 12, an electronic device according to some embodiments, when connected to an external display device, may output a home screen 1200 through the external display device. The home screen 1200 may include, for example, a first window 1210, a second window 1220, and a third window 1230. The first window 1210, the second window 1220, and the third window 1230 may include an execution screen of a first application, an execution screen of a second application, and an execution screen of a third application, respectively.

The first application may be, for example, an application that supports resizing of a window. The first window 1210 may include the execution screen of the first application and may be resized. When the first window 1210 is resized, the electronic device may modify a configuration of the execution screen of the first application, based on the size of the first window 1210. The electronic device may modify, for example, the size and arrangement of images, text, and/or icons included in the execution screen of the first application. In another example, the electronic device, when connected to the external display device, may change an execution mode of the first application. The electronic device, when receiving a request to execute the first application, may identify whether the electronic device is connected to the external display device. In the case where the electronic device is connected to the external display device, the electronic device may execute the first application in a first mode. In the case where the electronic device is disconnected from the external display device, the electronic device may execute the first application in a second mode. A UI of the first mode and a UI of the second mode may differ from each other. The electronic device may change the execution mode of the first application if there is a change in the connection state between the electronic device and the external display device.

The second application may be, for example, an application that does not support resizing of a window. The execution screen of the second application may have to be displayed in a portrait mode. The second window 1220 may include the execution screen of the second application. The second window 1220 may be generated at a ratio corresponding to the portrait mode. Resizing of the second window 1220 may not be allowed.

The third application may be, for example, an application that does not support resizing of a window. The execution screen of the third application may have to be displayed in a landscape mode. The third window 1230 may include the execution screen of the third application. The third window 1230 may be generated at a ratio corresponding to the landscape mode. Resizing of the third window 1230 may not be allowed.

According to some embodiments, when executing an application that does not support resizing of a window, the electronic device may decide whether to execute the application in a portrait or landscape mode. For example, the electronic device may display an execution screen of the application in a portrait or landscape mode specified to correspond to the application. In another example, the electronic device may display the execution screen of the application in the portrait or landscape mode in which the application was previously executed (in the orientation at the time of executing the application or in the orientation at the time of ending the application). Information about the mode in which the application was previously executed may be stored in a white list.

According to certain embodiments, an application may recognize that an execution screen of the application is displayed on the entire screen. For example, an application (e.g., the second application or the third application) that does not support resizing of a window may recognize that an execution screen of the application is displayed on the entire screen (e.g., the home screen 1200). For example, when the application is executed, the electronic device may convey, to the application, information about the size of a window (e.g., the second window 1220 or the third window 1230) in which the application is displayed. The application may recognize the received information about the size of the window as information about the size of the entire screen. In other words, the electronic device may fake out the application as if the execution screen of the application is displayed on the entire screen. The application may render the execution screen of the application, recognizing that the execution screen of the application is displayed on the entire screen. Since the electronic device provides the information about the size of the window to the application, the execution screen of the application may be rendered to fit the size of the window. The rendered screen may be output through the window.

When an input for resizing the first window 1510 is applied, the electronic device may display a red boundary line on the periphery of the first window 1510 to inform a user that the first window 1510 cannot be resized.

According to various embodiments, the electronic device may configure an additional window that displays information about the second type of window or a UI for control of the second type of window, and may display the additional window on an external display device such that the additional window is adjacent to the second type of window. For example, the electronic device may generate a second window 1520. The electronic device may dispose the second window 1520 near the top of the first window 1510. The second window 1520 may include buttons for performing functions, such as turn, back, minimize, close, and the like, on the first window 1510. The turn button may be included in the second window 1520 only in the case where the application displayed in the first window 1510 supports change of orientation (a portrait mode and a landscape mode). The turn button may not be included in the second window 1520 if the application displayed in the first window 1510 does not support change of orientation. The second window 1520 may display information, such as name, of the application displayed in the first window 1510.

FIG. 16 illustrates aspects of a transformation of coordinates by an electronic device according to various embodiments of this disclosure.

According to some embodiments, when an input is applied to a point in a second type of window, an electronic device may recognize coordinates where the input is applied, may transform the recognized coordinates, based on modified screen configuration information and the position of the second type of window, and may execute an operation of a target application that corresponds to the input to the transformed coordinates.

Referring to the non-limiting example of FIG. 16, the electronic device according to an embodiment, when connected to an external display device, may output a home screen 1600 through the external display device. The home screen 1600 may include a window 1610 that includes an execution screen of an application. The window 1610 may be the second type of window, and the application may be an application that does not support resizing of the window 1610. The electronic device may receive a user input to a first point 1611 that is intended for an input to a button 1612 in the window 1610. The electronic device may convey, to the application displayed in the window 1610, coordinates (e.g., (a, b)) of the user input to the first point 1611.

The application displayed in the second type of window may recognize that the application is displayed on the entire screen. Based on the received coordinates, the application may determine that the user input is input to a second point 1621. The electronic device may transform the coordinates, based on information about the resolution, density, and orientation of the home screen 1600 and information about the position of the window 1610. For example, the electronic device may transform the coordinates (a, b) into coordinates (x′, y′). The electronic device may convey the transformed coordinates to the application displayed in the window 1610, and the application may recognize an input to a third point 1622 and may execute an operation corresponding to the input to the third point 1622.

FIG. 17 illustrates aspects of a determination of screen orientation by an electronic device according to some embodiments of this disclosure.

According to certain embodiments, a target application may include a plurality of executable activities, and when one activity of the plurality of activities is executed, an electronic device may display an execution screen of the one activity in the same orientation as the orientation in which an execution screen of an activity executed prior to the one activity is displayed.

Referring to the non-limiting example of FIG. 17, the electronic device may execute an application and then execute a plurality of activities included in the application. The electronic device may execute a first activity. The electronic device may display an execution screen of the first activity in a first window 1710. The first activity may be displayed in only a landscape mode. The first window 1710 may be generated in the horizontal orientation to display the first activity.

The electronic device may execute a second activity after the first activity is executed. The second activity may be displayed in a portrait or landscape mode. The electronic device may display an execution screen of the second activity in a second window 1720. Since the second activity supports both the landscape mode and the portrait mode, the electronic device may generate the second window 1720 in the same orientation as that of the first window 1710 in which the execution screen of the first activity executed prior to the second activity is displayed. The second window 1720 may be generated in the horizontal orientation to display the second activity.

The electronic device may execute a third activity after the second activity is executed. The electronic device may display an execution screen of the third activity in a third window 1730. The third activity may be displayed in only a portrait mode. The third window 1730 may be generated in the vertical orientation to display the third activity, irrespective of the second window 1720.

The electronic device may execute the second activity again after the third activity is executed. The electronic device may display an execution screen of the second activity in a fourth window 1740. Since the second activity supports both the landscape mode and the portrait mode, the electronic device may generate the fourth window 1740 in the same orientation as that of the third window 1730 in which the execution screen of the third activity executed prior to the second activity is displayed. The fourth window 1740 may be generated in the vertical orientation to display the second activity.

The electronic device may execute the first activity again after the third activity is executed. The electronic device may display an execution screen of the first activity in a fifth window 1750. Since the first activity is displayed in only the landscape mode, the fifth window 1750 may be generated in the horizontal orientation to display the first activity, irrespective of the fourth window 1740.

For the convenience of description, the activities are illustrated in the non-limiting example of FIG. 17 as being displayed in the first to fifth windows 1710 to 1750. However, the first to fifth windows 1710 to 1750 may, according to some embodiments, be the same window. For example, the second window 1720 may be the same window as the first window 1710, the third window 1730 may be transformed from the second window 1720, the fourth window 1740 may be the same window as the third window 1730, and the fifth window 1750 may be transformed from the fourth window 1740.

According to at least one embodiment, where the electronic device executes an activity that supports both a landscape mode and a portrait mode, the electronic device may display an execution screen of the activity in a specified mode of the landscape and portrait modes if a history of an activity executed prior to the activity does not exist.

FIG. 18 illustrates aspects of a change of image orientation by an electronic device according to some embodiments of this disclosure.
